NAME `Tickit::Widget::SegmentDisplay' - show a single character like a segmented display DESCRIPTION This class provides a widget that immitates a segmented LED or LCD display. It shows a single character by lighting or shading fixed rectangular bars. STYLE The default style pen is used as the widget pen, though only the background colour will actually matter as the widget does not directly display text. The following style keys are used: lit => COLOUR unlit => COLOUR Colour descriptions (index or name) for the lit and unlight segments of the display. CONSTRUCTOR new $segmentdisplay = Tickit::Widget::SegmentDisplay->new( %args ) Constructs a new `Tickit::Widget::SegmentDisplay' object. Takes the following named arguments value => STR Sets an initial value. type => STR The type of display. Supported types are: seven A 7-segment bar display. The display can also be blanked with the value " ". seven_dp A 7-segment bar display with decimal-point. To light the decimal point, append the value with ".". colon A static `:' symb A unit, prefix symbol or other character. The following characters are recognised: V A W Ω F H s G M k m µ n p + - % Each will be drawn in a style approximately to fit the general LED shape display, by drawing lines of erased cells. Note however that some more intricate shapes may not be very visible on smaller scales. use_unicode => BOOL If true, use Unicode block-drawing characters. If false, use only coloured erase cells using the background colour. use_halfline => BOOL If true, vertical resolution of rendered block characters is effectively doubled by using half-filled Unicode block-drawing characters. Setting this option implies `use_unicode'. thickness => INT Gives the number of columns wide and half-lines tall that LED bars will be drawn in. Note that unless `use_halfline' is set, this value ought to be an even number. Defaults to 2. ACCESSORS value $value = $segmentdisplay->value $segmentdisplay->set_value( $value ) Return or set the character on display AUTHOR Paul Evans
